Low frame rate with Win XP

[2ndgunman]

Last week I switched from Windows ME to XP. With ME I was getting around 10000 3DMarks and 80-100 fps on Ghost Recon. With XP I'm getting around 8300 3DMarks and only 40-60 fps. I was using the most recent detonators (41.09??) with ME. I've tried both 40.72 and 41.09 on XP and didn't see any real difference in 3DMarks or frame rate.

Like I said, I just changed OS last week.....so it's possible I just have something set incorrectly.

If anyone has any ideas I'd really appreciate your advice.

Did you install the latset motherboard drivers.
Is AGP enabled in windows.

Also, did you fix the refresh rate issues (v-sync disabled?). I haven't used Nvidia in a while, but there are a couple of refresh fixes for them.

As far as the drivers go............
I tried to D/L the newest VIA 4in1 drivers, but VIA's website says that if you have a hybrid chipset motherboard (AMD North and VIA south) to get the drivers from the MB maker. ASUS website doesn't list 3in1 drivers for XP. I've got e-mail in to their tech support already and am just waiting for a reply.

I didn't think to turn off V-sync. Let me try to remember how to do that and I'll give it a try.
